Applications of AC Mixed Flow Fans


An AC mixed flow fan is a type of fan that combines features of both axial and centrifugal fans. This hybrid design allows for efficient airflow with moderate pressure capabilities, making them suitable for a wide range of ventilation and cooling applications. Here's a detailed overview of AC mixed flow fans and their features:

Features of AC Mixed Flow Fan

1. Hybrid Design: AC mixed flow fans combine the characteristics of axial and centrifugal fans. They feature a mixed flow impeller design that combines the straight airflow path of axial fans with the increased pressure capabilities of centrifugal fans.

2. Impeller Design: The impeller of an AC mixed flow fan typically consists of curved blades that are angled to direct airflow both axially and radially. This design allows for efficient airflow with moderate pressure generation.

3. Airflow Efficiency: AC mixed flow fans are known for their high airflow efficiency, making them suitable for applications where a balance between airflow and pressure is required. They can move large volumes of air while maintaining relatively consistent pressure levels.

4. Compact Size: Compared to traditional centrifugal fans, AC mixed flow fans often have a more compact design, making them suitable for installations where space is limited.

5. Quiet Operation: AC mixed flow fans generally produce less noise compared to centrifugal fans with similar airflow and pressure capabilities. This makes them suitable for applications where low noise levels are desired.

6. Mounting Flexibility: These fans can be mounted in various orientations, including horizontal, vertical, or angled positions, providing flexibility in installation.

7. Variable Speed Control: Many AC mixed flow fans are equipped with variable speed control options, allowing users to adjust the fan speed to meet specific ventilation or cooling requirements.

8. Thermal Protection: Some models may feature built-in thermal protection mechanisms to prevent overheating and ensure safe operation.

9. Durable Construction: AC mixed flow fans are typically constructed with durable materials such as metal or high-grade plastics, ensuring long-term reliability and performance.

Applications of AC Mixed Flow Fans

1. Ventilation Systems: AC mixed flow fans are commonly used in ventilation systems for buildings, warehouses, parking garages, and industrial facilities to provide fresh air circulation and exhaust stale air.

2. Air Conditioning Systems: These fans can be used in air conditioning systems to assist with air distribution and circulation, helping to maintain comfortable indoor temperatures.

3. Cooling Towers: AC mixed flow fans are often employed in cooling towers to enhance heat dissipation by promoting airflow through the tower fill media.

4. Heat Exchangers: They can be utilized in heat exchangers to improve thermal efficiency by facilitating air movement across heat exchange surfaces.

5. Electronic Enclosures: AC mixed flow fans are used for cooling electronic enclosures, cabinets, and racks to prevent overheating of sensitive electronic components.

6. Refrigeration Systems: They are employed in refrigeration systems to assist with heat rejection and maintain optimal operating temperatures.


AC mixed flow fans offer a balanced combination of airflow and pressure capabilities, making them versatile solutions for various ventilation and cooling applications. With their hybrid design, compact size, and quiet operation, they are suitable for both residential and commercial settings where efficient air movement is required. When selecting an AC mixed flow fan, consider factors such as airflow efficiency, pressure capabilities, size, mounting options, and speed control features to ensure it meets the specific requirements of your application.
